H5O.link

Create hard link to specified object

Syntax

H5O.link(obj_id,new_loc_id,new_link_name,lcpl_id,lapl_id)

Description

H5O.link(obj_id,new_loc_id,new_link_name,lcpl_id,lapl_id) creates a hard link to an object, where new_loc_id and new_link_name specify the location. lcpl_id and lapl_id are the link creation and access property lists associated with the new link.

H5O.link is designed to add additional structure to an existing file so that, for example, an object can be shared among multiple groups.

Examples

Create a hard link from group '/g2' to the dataset '/g1/ds1'.

plist_id = 'H5P_DEFAULT';
fid = H5F.create('myfile.h5','H5F_ACC_TRUNC',plist_id,plist_id);
gid1 = H5G.create(fid,'/g1',plist_id);
space_id = H5S.create_simple(1,10,[]);
ds1 = H5D.create(gid1,'ds1','H5T_NATIVE_INT',space_id,plist_id);
gid2 = H5G.create(fid,'/g2',plist_id);
H5O.link(ds1,gid2,'ds2',plist_id,plist_id);
H5D.close(ds1);
H5S.close(space_id);
H5G.close(gid2); H5G.close(gid1);
H5F.close(fid);
